CHONGQING, China – As part of China’s Sponge City programme to increase resilience to the risk of floods, SUEZ has been awarded a contract to optimise stormwater systems in the new eco-district of Yuelai, in Chongqing.
The Sponge City programme seeks to improve cities’ resilience by optimising the capacity of sewer systems to harvest and treat these stormwater volumes.
Among the 30 cities selected by the Chinese government, Chongqing is a pioneer in the development of a solution for the optimisation of sewer and stormwater networks.
Rising urbanisation in China, along with the increase in extreme weather events due to climate change, increase the risks of floods and pollution in urban areas.
Stormwater is responsible for 50% of the pollution flowing into rivers and beaches in urban areas.
As part of the project, SUEZ will deploy its AQUADVANCED® Urban Drainage, a digital solution allowing local authorities to monitor their sewer and stormwater networks in real time to mitigate the risk of flooding and control the quality of discharges into the natural environment.
The solution will be deployed on a surface area of 18.7 km2 in the new eco-district of Yuelai in Chongqing, representing an investment of €4 million and will be launched in April 2017.
SUEZ said: “By centralising and analysing all these data, the software solution will enable authorities to protect the population from the risk of floods and limit the pollution of the Yangtze, the longest river in Asia and an essential water supply for populations.”
The urban drainage solution has previously been deployed in 20 cities around the world, including Paris, Barcelona and Singapore.
